Rocking exercise device

ABSTRACT

Rocking exercise device including at least one rocking member having an arched bottom face. A top face of the rocking member is provided with a front step board and a rear step board oppositely inclined toward the center. The opposite ends of the front step board and rear step board of the rocking member respectively have a downward extending front projecting block and a rear projecting block. The rocking member is equipped with two fastening straps at the front and rear step boards. A shaft hole transversely passes through the rocking member. A center point of the shaft hole and a center point of the arch of the bottom face of the rocking member are not at the same position. One end of a shaft rod is fitted in the shaft hole and the other end of the shaft rod is fitted in the shaft hole of an adjacent rocking member.

BACKGROUND OF THE INVENTION

[0001] The present invention is related to a rocking exercise device,and more particularly to a rocking exercise device that provides backand forth and left and right rocking exercising effect for a user. Also,the rocking exercise device can be used more safely.

[0002]FIG. 13 shows a conventional rocking exercising shoe having anarched base 7. The arched base 7 has an arched bottom face 71. The topface of the base 7 is provided with a front step board 72 and a rearstep board 73 inclined toward each other for a user to step thereon. Thefront and rear ends of the bottom face 71 respectively have twoprojections 74. When the base 7 swings back and forth, the projections74 contact with the ground to restrict the rocking amplitude of the base7.

[0003] In use, a user's foot steps on the base 7 with the front portionof the sole positioned on the front step board 72 and the heelpositioned on the rear step board 73. The arched bottom face 71 swingsback and forth on the ground so as to stretch and exercise the musclesof the leg.

[0004] When the base 7 swings back and forth, the projections 74 contactwith the ground to restrict the rocking amplitude of the base 7 and thusprevent the user from falling down.

[0005] However, the distance between the two projections 74 is too shortso that the rocking amplitude of the base 7 is limited and an expectedexercising effect can be hardly achieved. Moreover, the projection 74simply slightly protrudes from the bottom face 71 of the base 7 so thatthe stopping effect is poor. In the case that the user excessivelyswings and the rocking angle of the base 7 exceeds the stoppable angleof the projections 74, the user may still fall down forward or backward.

[0006]FIG. 14 shows an improved rocking exercise device in which twoside plates 75 are respectively locked on two sides of the base 7. Twostopper sections 76 are respectively formed on front and rear ends ofeach side plate. The stopper sections 76 are respectively positioned onouter sides of two ends of the arched base 7. When the base 7 swings,the stopper sections 76 contact with the ground to prevent the base 7from over-rocking, while the base 7 can have larger rocking amplitude.

[0007] However, the side plates 75 are fixed on two sides of the base 7by screws. After a period of use, the screws tend to loosen and the sideplates 75 may detach. This results in danger in use.

[0008] Furthermore, such exercising shoe can simply swing back and forthto stretch the leg of the user, while the other parts of the user cannotbe exercised with such exercising shoe.

SUMMARY OF THE INVENTION

[0009] It is therefore a primary object of the present invention toprovide a rocking exercise device including at least one rocking memberhaving an arched bottom face. A shaft rod is pivotally fitted betweentwo adjacent rocking members. A center point of the shaft rod and acenter point of the arch of the bottom face of the rocking member arenot at the same position, whereby the rocking members will eccentricallyswing. Therefore, when a user's feet step on the rocking members andswing back and forth, the rocking members will at the same time swingleft and right. Accordingly, the muscles of the user's leg are stretchedand the waist of the user is twisted to exercise the whole body of theuser.

[0010] It is a further object of the present invention to provide theabove rocking exercise device which further includes a frame body onwhich two rocking members are pivotally disposed. A handlebar isdisposed on an upright stem of the frame body for a user to hold whenstepping on the rocking members. Therefore, the safety in use of therocking exercise device can be ensured.

[0011] It is still a further object of the present invention to providethe above rocking exercise device in which a leaf spring is disposedunder the bottom of the rocking member, whereby a user can jump up anddown to exercise.

[0012] The present invention can be best understood through thefollowing description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] Please refer to FIGS. 1 to 3. According to a first embodiment,the rocking exercise device of the present invention includes at leastone rocking member 1 having an arched bottom face 11 in contact with asupport face. A slip-proof pad 111 is paved under the bottom face 11 toincrease the frictional force against the support face. The top face ofthe rocking member 1 is provided with a front step board 12 and a rearstep board 13 oppositely inclined toward the center for a user to stepthereon. Multiple domed protuberances 14 are distributed over the frontand rear step boards 12, 13 to provide massaging effect for the user'sfeet.

[0028] An upright wall 15 is formed on rear edge of the rear step board13. The upright wall 15 has a profile corresponding to that of the heelof human foot, whereby the heel of the user is stopped from rearwardslipping out.

[0029] The rocking member 1 is formed with a shaft hole 17 transverselypassing through the rocking member 1. The center point C1 of the shafthole 17 and the center point C2 of the arch of the bottom face 11 arenot at the same position. Therefore, the rocking member 1 willeccentrically swing. One end of a shaft rod 2 is fitted in the shafthole 17. The other end of the shaft rod 2 is fitted in the shaft hole 17of an adjacent rocking member 1. A sleeve 21 is fitted around the middlesection of the shaft rod 2 to stop the opposite sides of the two rockingmembers 1 and space the two rocking members 1 from each other by acertain distance. One end of the shaft rod 2 has a stop flange 22, whilethe other end of the shaft rod 2 is formed with a thread 23. By means ofa nut 24, the shaft rod 2 can be fixed on the two rocking members 1.

[0030] In use, as shown in FIG. 4, a user can sit and step on the tworocking members 1 with both feet. The front portion of the sole ispositioned on the front step board 12 and the heel is positioned on therear step board 13. By means of the arched bottom faces 11, the rockingmembers 1 swing on the ground back and forth. When the user presseshis/her feet forward or backward, the muscles of the instep and thefront side of the leg are stretched and exercised.

[0031] Referring to FIG. 5, when rocking back and forth, the centerpoint C1 of the shaft hole 17 of the rocking member 1 and the centerpoint C2 of the arch of the bottom face 11 are not at the same position.Therefore, the rocking member 1 will eccentrically swing. When theuser's feet step on the rocking members 1 and swing back and forth, theshaft rod 2 will be deflected, whereby the two rocking members 1 willalso swing left and right. Accordingly, the waist of the user will swingalong with the rocking, members 1. In cooperation with the rocking ofboth hands in reverse direction, the whole body of the user can beexercised.

[0032]FIGS. 6 and 7 show a second embodiment of the present invention,in which the rocking exercise device has a frame body 3 on which tworocking members 1 are pivotally disposed. A pivot seat 31 is disposed onthe middle section of the frame body 3. The pivot seat 31 has threepivot plates 311 at equal intervals. Each pivot plate has a circularhole 312. The middle pivot plate 311 divides the pivot seat 31 into twospaces in which the rocking members 1 are respectively pivotallydisposed. The shaft rod 2 of the rocking members 1 extends through thecircular holes 312 of the three pivot plates 311. Two ends of the shaftrod 2 are respectively fixed in the circular holes 312 of two outerpivot plates 311. Accordingly, the rocking members 1 can swing back andforth on the pivot seat 31 of the frame body 3.

[0033] The frame body 1 has an upright stem 32 at one end opposite tothe pivot seat 31. The upright stem 32 is telescopic to adjust thelength in accordance with the height of a user. A handlebar 33 istransversely disposed on top end of the stem 32 for a user to hold.

[0034] The upright stem 32 is telescopic to adjust the height of thehandlebar 33 in accordance with the height of a user. Moreover, a user,especially a child or a user with poor balance feeling can hold thehandlebar 33 in exercise so as to ensure safety.

[0035]FIGS. 8 and 9 show a third embodiment of the present invention, inwhich the opposite ends of the front step board 12 and rear step board13 of the rocking member 1 respectively have a downward extending frontprojecting block 121 and a rear projecting block 131. The free ends ofthe front and rear projecting blocks 121, 131 respectively have stoppersections 122, 132 tangential to the arch of the bottom face 11. Aslip-proof cap 133 is fitted on each stopper section 122, 132 to contactwith the ground. Each rocking member 1 is equipped with two fasteningstraps 16 at the front and rear step boards 12, 13. The fastening straps16 are wound over the foot of the user to fix the foot on the rockingmember 1. In this embodiment, the fastening strap 16 is a strap havingloop-hook tape.

[0036] In this embodiment, when a user wears the rocking members 1 towalk and exercise, the shaft rod 2 is detached to separate the tworocking members 1. When walking, the feet of the user will press therocking members 1 forward, whereby the muscles of the instep and frontside of the leg are stretched and exercised.

[0037] The stopper section 122 of the front projecting block 121 istangential to the arch of the bottom face 11. Therefore, when the userwalks and the front section of the sole is pressed down, the stoppersection 122 of the front projecting block 121 and the bottom face 11both well contact with the ground. In addition, the slip-proof pad 111provides a slip-proof effect to prevent the user from slipping down.

[0038]FIGS. 10 and 11 shows a fourth embodiment of the presentinvention, in which an arched leaf spring 4 is disposed under the bottomof the rocking member 1. Two ends of the leaf spring 4 are respectivelyformed with two insertion sections 41 in which the front and rearprojecting blocks 121, 131 of the rocking member 1 are inserted. Bymeans of the resilience of the leaf spring 4, a user can jump up anddown to exercise.

[0039]FIG. 12 shows a fifth embodiment of the present invention, inwhich two transverse beams 6 are connected between the two rockingmembers 1 respectively under the front and rear step boards 12, 13.Accordingly, a user's feet can step on the rocking members 1 and rollback and forth. The upper half of the user's body can tilt backward orforward to keep in balance. This can exercise the waist of the user.
